MF-USHT035KX-2 is a PTC resettable fuse designed for overcurrent protection in automotive and high-temperature electronic applications. This 1210 surface mount component features a maximum voltage rating of 30V, a hold current of 0.35A at 23°C, and a trip current of 1.75A, with a resistance of 0.4 O at 23°C. The device operates reliably across an extended temperature range from -40°C to +125°C and incorporates low thermal derating characteristics to maintain higher hold currents at elevated temperatures. It is AEC-Q200 Rev-C compliant and RoHS compliant, making it ideal for engine control modules, automotive circuitry protection, and general electronic equipment requiring resettable fault protection in demanding thermal environments.
